How about stouts, all varieties of them. Simply cos I like the idea of brewing an oatmeal coffee stout. But it's a broad enough range that we might get some interersting varieties (coffee/vanilla/cream etc).
Yes it's summer, but it IS Ireland, so there's a 50/50 chance the weather will be warm or cold. To hedge the bets the other style can be something more 'summery'..... Heavy and light, black and pale, yin and yang....
Just a thought sure..
